Wow some of that Mir Station footage is the best - and the footage from the broken tether. Unidentified is right - but they can be so many things, definitely not ice crystals. Science needs to take this seriously and provide its findings to the public with absolute evidence for their conclusions one way or another. Until then it is amazing phenomena and some of the objects changing direction or slowing down then speeding up had me gob smacked.

Finnaly it went through! libstaK i concure some of those videos are really messed up, i didnt know what to think but i dont think everything is ice crystals too. But how did this guy obtain footage from ISS,MIR? And some phenomena in there is really incredible. If someone was to show this to nasa they would probably say its fake or photoshoped... XD
